IMPROVEIIBNT IN BXTRACTING SPIRITS QF TURPBNTI'NE FROMPW WOUD.

meeneem :em-maremma um nmz ma mien; pandora sma- To allwhom ttm/ i1 Beit known thaty I, IAMus'D. STANLEY, of Wilmington, in the county dfNewHanover, in the State 'ofNorth Carolina, havefflnvented a new andimproved Mode of Extracting, Purifying, and Separating, by one andthesame Process, from Pine Wood, White Spirits cf Turpentine, Oil, Tar, andIuflammable Gas, leaving a. residuum of charcoal;l and I do herebydeclare that the following is a ihll and exact description thereof,

dt=oth6t Silitable, substanceor. substances,4

thrcughswhich-the spirits of turpentine, oil, tar, 8vo.,

are passed in-,theform vapor, and so puried, and ieuce carried to theccndensers X E, iixedin cisterns or cast-iron, or other suitablesubstance.

The door T is closed air-tight, by means of screw b and bracket l. l

P is a disk-valve, opened or closed by means of rod E and handle o.

Z is a stop-cock. Y

The top of grate-bars O is six inches abovethe bottom of retort G.

Wireuae supports, i i, are stretched across purifier to sustain orseparate purifying-substance or substances. v

Purliier K has, at one end, the perforated sheet of iron F, and wiregauze stretched across it at Y, to retain in 'place thepurifying-substance L.

The condensers E and X are of copper, or other suitable material, and ofthe form of a hollow cylindrical ring, and xed. in cisterne O and D,which are kept full of wie water.

Condenser X has oneeock, near its bottom, for running oii its contents.

Uondenser E has theeock d for running oii oil, tar Sto., and cock o forescapo cf inllammable gas.

Oock f is fm' any residue of tar, .Sta

Gauge-cook o is for regulating the amount of water, introduced into theretort through pipe s while distillation ci white spirits is going on.`

The retort G, having been filled o1; charged with pine wood, and waterintroduced to the depth ci top of grateand D. The retort G andpuriers 11and K may be of wrought bars O, the doorT cltsed, cock Z closed, andvalve P opened, heat is applied, either as shown in accompanyingdrawings, by fire in the furnace underneath the retortthe draughtpassing through fines W W, over the retort and oii' through smoke-stackH, or by the introduction of superbeated steam into the retort.

The white spirits of .turpentine now pass off in vapor through valve P,purifer I, and pipe V, into condenser X, and are thence drawn olipurified and free from As sconas these s'pirits begin to show color,valve colored.spiritsoil. tar pag I puri lier K, into condenser lh.,

Thel pyroligneous and acetic acid retained in the pm'ifyingsubstances Land M, rated from them with less tmuble and expense than by the ordinarymethod.

The advantage this method of obtaining white spirits from wood has overany other heretofore known or used is, that byclosing the valve P,'assoon as the spirits .passing through it begin to show color, thepurilier I and contents, pipe V, and condenser X, are kept clean, sothat white spirits can be run through them from subsequent charges;whereas, if coloredspirits were suered to pass through themonce, theywould have to be carefully cleaned (a' very diiiioult matter) beforethey could run white spirits again, and colored spirits white, or nearlyso.

What I claim as my invention, and desire to secure by Letters Patent,isv A new method of extracting, separating, and purifying, by one andthe same process, ilom' pine wood, white spl 'ts of turpentine, oil,tar, and inflammable gas, byapplying to a retort two purifiers connectedwith two condensers, in the manner and with the appliances hereindescribed, or any other substantially the same, and which will producethe intended etiect.
